What is the difference between pneumatic water well drilling machines and hydraulic water well drilling machines

These two types of water well drilling machines can actually be easily distinguished.

Pneumatic water well drilling machines require an air compressor for construction. They have fast footage and high efficiency, and are suitable for most rock formations. The investment cost is relatively high. Hydraulic water well drilling machines work by supplying water through mud pumps, and can handle a wider range of formations. They can drill in all soil layers, rock layers, and complex formations, with low investment and moderate efficiency. It mainly depends on individual choices

Hydraulic drilling rigs use coring tools for coring through hydraulic pressure, while pneumatic drilling rigs directly impact rocks and drill them down. The price of pneumatic drilling rigs is relatively higher, and they also need to be equipped with an air compressor for use.
